Specimen Requirements | |||||
Specimen Type: | Stool specimen or rectal swabs in enteric transport media (Cary-Blair). | ||||
Patient Preparation: | The patient should be instructed not to take any antacids, oily laxatives, or anti-diarrheal medications unless prescribed by the physician. | ||||
Collection Instructions: | Use an Enteric Transport Media (Cary-Blair) Vial, clearly labeled with two unique identifiers (patient's name and unique identifier) and the date of collection. ETM is buffered and normally appears red. If the liquid is yellow, an acidic shift has occurred and the vial should not be used. Pass the stool into a clean, dry, plastic disposable container or place a large plastic bag or kitchen wrap over the toilet seat to catch the specimen. DO NOT MIX URINE OR WATER WITH THE STOOL SPECIMEN. Formed or semi-formed stool: Using the spork built into the lid, add approximately three spoonfuls of firm stool, or five spoonfuls of soft stool to the vial until the liquid reaches the red "fill line". Any blood or mucous should be included. Wash hands thoroughly. |

Expected Results: | |||||
No Yersinia species isolated, Yersinia species identification. | |||||

Diagnose Yersinia-associated diarrhea in patients with appropriate exposure history or risk factors. The organism Yersinia enterocolitica can survive cold temperatures (refrigeration) and is often linked to food products or in blood products causing a potential transfusion reaction. | |||||
